[Q] Upgrading my S4 still running 4.2.2 while keeping root

Hi everyone! I need some help updating my S4. I rooted it awhile back and I'm very much of the mindset of "if it ain't broke, don't fix it," so since it was doing everything I wanted, I've just left it alone and kept dismissing the prompt to install the OTA update. Now I'm having some issues and want some features of the newer versions of Android, so I was looking around for the best way to update it while keeping my root access. All the guides I can find, however, talk about upgrading from 4.3 to 4.4 or 4.2 to 4.3. So I was wondering...

1. What version should I update to? On my last phone, a Droid Bionic, one of the big Android version updates ran so horribly on it that I ended up getting a new phone. Because of that, I'm very nervous about updating my phone and having the performance suffer.

2. There must be a way to go straight from 4.2.2 to whatever version I choose, right? Do I need to go dig up some old guides on how to update my phone so that the most recent guides are relevant?

I hope I'm not being a super noob about this. I tried Googling around, and I'm pretty tech savvy but just haven't had the time to keep up with recent developments, so some guidance would be very helpful!

About my phone:
Verizon Galaxy S4
Model #: SCH-I545
Android version: 4.2.2
Baseband version: I545VRUDMI1

Thanks so much!

Find out what base band you have, MDK, ME7?

If MDK, install recovery download rom.

Anything other check this thread out:

Advice, better read about the bugs and issues each version has. Once you go up, you cannot go back. Not ever, no never.

Well if he is one of those few lucky MDK people he could hop around versions as he please. But most of them already know that *Grin*

I put the baseband version of my phone in my original post. It's I545VRUDMI1. Or am I missing something? So that means I should use Odin to flash whatever rom I decide to go with, right? So if I went with something like this 4.4.4 Google Play Edition I can use Odin to put it on my device? But then if I decide I don't like that rom for whatever reason, I can't redo it with any roms based on an earlier version (4.4.2, 4.3, etc), but other 4.4.4 roms would work?

Thanks so much for the help!

You need a custom recovery to flash that Play Edition ROM which is not possible with your MI1 baseband.

So how do I know/find which roms will work?

Here's a pretty good thread explaining the different basebands.

OK, I think I'm starting to get it. So should I use Odin to flash the rom listed under "Recover by re-flashing stock" in this thread? Or should I use safestrap? What's the difference?
